Vacon Beam Pump Application

1. Introduction

Select the Beam Pump Application in menu M6 on page

S6.2

.

The purpose of the Beam Pump Application is to keep a constant stroke time (SPM) by adjusting the

internal frequency reference. The control principle is to give a proper current limit for normal

operation so that during motoring cycle the motor's actual speed is less than reference but during

generating the motor speed is allowed go higher than reference, keeping the average SPM constant.

With balanced load, the application uses two different references for downstroke and upstroke.

2. Commissioning

Figure 1. Beam Pump typical torque demand.

2.1 Commissioning unbalanced load

1. Set motor name plate values

− Motor nominal current must be set before the operation current limits.

2. Set proper values for START operation

−

Start Time

par. 2.1.18.2 Default 10.0 s

−

Starting Current Limit

par. 2.1.18.3 Default 110% * I

n

− Starting acceleration time (

Acceleration time 2

) P2.4.3 Default 10.0 s

3. Set proper value for

Normal Current Limit

(P2.1.18.1)

− Speed drops during motoring operation but it will reach the reference before the

generating cycle. If the speed drops to boost limit in normal operation you should

increase the current limit.

− If the motor load increases there is no need for higher current limit because the

control principle is to increase the speed on generating side and use the pump's own

inertia to overcome higher load.

4. Set proper values for boost

−

Boost ON Limit

par. 2.1.18.4 Default 15.00 Hz

−

Boost OFF Limit

par. 2.1.18.5 Default 20.00 Hz

−

Boost Current Limit

par. 2.1.18.6 Default 120% * In

Boost ON Limit

should be near the minimum frequency, which is reached during normal

operation.

6. Set

SPM Regulator Maximum Step

. (P2.1.19.3) The parameter defines the frequency step

which can be made to compensate load changes. A higher value shortens the response

time, but may cause hunting on control.

7. Set

SPM regulator Gain

. (P2.1.19.2) Defines the gain of control. If the parameter is set to

100% SPM error is corrected completely within

SPM Regulator Maximum Step

. It is typical

that on start situation the adjustment is hunting. If hunting continues over 3-4 minutes you

should decrease the adjustment gain.

2.2 Commissioning balanced load

The commissioning of a balanced load is done in the same way as of an unbalanced load except for

the normal current limit. You have to select control method for balanced load.

1. Use higher normal current limit (P2.1.18.1) than in the unbalanced mode. In the balanced

mode, there is no clear generating side in torque.

2. Select proper control method at

Balanced mode

P2.1.20.1.

Figure 2. Typical torque demand of a beam pump.

. This parameter is defined as percentage of torque. When torque

is above this limit higher reference allow time counter is calculating.

2. P2.1.21.2

Higher Reference Allow Time

. Time how long torque most be higher than P2.1.21.1

so that higher reference is permitted.

3. P2.1.21.3

First Torque Middle Point

. Torque point where High reference is activated. When

high reference allow time is full and motor torque goes below this parameter higher reference

is activated.

4. P2.1.21.4

Minimum Time at Higher Reference

. Minimum time until low reference is permitted

after high reference activaton.

5. P2.1.21.5

Minimum High Reference Cycle Time

. Minimum time until high reference can be

activated again.

. Time how long torque most be higher than P2.1.21.6

so that lower reference is permitted.

low reference allow time is full and motor torque goes below this parameter lower reference

is activated.

5. Description of parameters

5.1 Basic parameters

2.1.1 Minimum frequency

Defines the frequency limits of the frequency converter.

The maximum value for parameters 2.1.1 and 2.1.2 is 320 Hz. The software will

automatically check the values of parameters 2.1.13, 2.1.14, 2.3.10 and 2.7.2.

2.1.2 Maximum frequency

Defines limit for output frequency, this limit could be reached when motor is generating

side and drive tries to compensate DC-link voltage rising. If limit is reached and motor is

still accelerating due the pump mass of inertia over voltage trip may occur, if this happens

set maximum frequency higher.

2.1.3, 2.1.4 Acceleration time 1, deceleration time 1

These limits correspond to the time required for the output frequency to

accelerate from the zero frequency to the set maximum frequency (par. 2.1.2).

2.1.5 Nominal voltage of the motor

Find this value U

n

on the rating plate of the motor. This parameter sets the voltage at the

field weakening point (parameter 2.6.5) to 100% x U

nmotor

.

2.1.6 Nominal frequency of the motor

Find this value f

n

on the rating plate of the motor. This parameter sets the field weakening

point (parameter 2.6.4) to the same value.

2.1.7 Nominal speed of the motor

Find this value n

n

on the rating plate of the motor.

2.1.8 Nominal current of the motor

Find this value I

n

on the rating plate of the motor.

2.1.9 Motor cos phi

Find this value “cos phi” on the rating plate of the motor.

2.1.10 I/O frequency reference selection

Defines which frequency reference source is selected when controlled from the I/O

control place. Default value is 0.

0 = Analogue voltage reference from terminals 2—3, e.g. potentiometer

1 = Analogue current reference from terminals 4—5, e.g. transducer

2 = Keypad reference from the Reference Page (Group M3)

3 =Reference from the fieldbus
